coLLArsIBLr. SHADE.

To all 'whom t may concern.'

Be it known that I, MICHAEL E. BRADY, a citizen ofthe United Stat-es,residing at Chicago, in the countyr of Cook and State of Illinois, haveinvented certain new and useful Improve-ments in Collapsible Shades, ofwhich thefollowing is ay specification.

This invention relates to improvements inV collapsible shadesl and isintended principally for use as a night shade.

Theobj ect of the V invention is to provide a collapsible and easilyportable shade which may be afiixed to an ordinary gas jet or fixtureforuse in a sick-room wherey it is important to have alight immediatelyavailable and yet where it is desirable to prevent direct rays koflight-from reaching the patient, except at intervals.

In mu invention I have provided a device which may be readily carried bya nurse in her hand bag andapplied to the gas jet in a sick-room insuoli amanner as to cause the light from the jet to be reflected againstthe ceiling, thus providing indirect illumination in the room, and atthe same time permitting, by a slight movement, the shade `to loe openedwhen full lighting effect of the gas jet is desired.

Other objects will be 'set forthl and made apparent in the followingspecification and the accompanying drawing, in which-d Figure 1 is aside elevation of my device attached to a gas jet, the side beingthrownopen. Fig. 2 is a plan View of the same in closed position. Fig. 3 is anend 'elevation showing the device in collapsible position.

Like, numerals `refer kto like elements throughout the drawing. Mydevice comprises preferably Vthe three plates 10, 11 and 12, preferablytrapezoidal in forni, the-side plates 1l and 12 each beingi with theoutwardly extending beadV 16 adapted to seat in'and be carried by thegroove 15 when in what I ter-m closed position, as indicated in Fig. 2.The upper edges of all three sides 10, 11v andv 12 are overturned, asshown in Fig. 1 of the drawings, also the lower edges of sides 11 and12.l

The base 17, approximately triangular in form, is hinged at the base ofside 10. .This

base'is` provided with a centrally located Specification of LettersPatent.

through the aperture in the base plate 17 and the flap 20, the collars18 and 22 serving to hold the device firmly in position on said gas Jet.Y

It will be apparent that as shown in Fig. 1 the plates 17 and 20 willlie approximately in parallel planes and will serve to firmly retain themain plate 10 in iixed position. The side plates 11 and 12 yare providedwith the circular depressions 24 and 25, respectively,for a purpose tobe described.`

`When the device is to be collapsed for carrying or shipping, the plate20 is swung up into contact with the inner face of the main plate 1()and the base plate 17 is swung up into contact with the outer side 'ofthe main plate 10 as illustrated'v in Fig. 3. The side plates 11 and 12may be swung fiat against the respective surfaces of the main plate 10,the kdepressions 24: and 25 forming a seat for the collars 18 and 22,respectively, so that the device may be carried folded flat in aposition which will occupy very little room. rIhe device when attachedvto the gas jet or lighting fixture 23, as illustrated in Fig. 1, mayhave the sideplates 11 and 12 in open position, as shown, in whichcasethe full lightA of the jet will be'allowed to penetrate the room inwhich it is located. Whenthe sides 11 and 12 are swung up intocontacting position the bead or rib 16 may loe seated in the groove 15serving to retain the device shown in the position in Fig. 2, in whichposition the rays of light from the jet will be reflected upwardly,serving to shade the room, only indirect illumination being permitted.When the nurse or attendant finds it desirable to administer medicine ortreat the patient, the side plates 11 and y12 may be disengaged andpermitted vto drop into the position shown in Fig. 1, in which event thedirect rays of light will ybe permitted'to strike the patient. Tofurther the reflecting effect, the main and side plates 10, 11 and 12,respectively, are constructed of some such material as aluminum, whichprovides a highly reflective surface and at the' same time is of lightweight and durable construction. In the event. that t-hepatient requiresclose examination during the night as for throat trouble etc., the mainplate may be so arranged with respect to the jet that the direct rayswill be reflected directly toward trapezoidal side plates, one hinged toeach the patient.

It will be apparent that by constructing"V these main and side platestrapezoidalin" form and arranging them as shown, the device willapproximate a truste-pyramid in shape and reflection of the raysupwardly ywill thereby be enhanced as will be'apparent.

While I have shown and described my device with more or lesspart-icularity, I do not wish to b-e unduly restricted to such showingand description beyond the scope of the appended claims.

I claim:

l. In a collapsible shade, the combination with a main plate, of aplurality of side plates hinged to the side edges of the main plate,means for'securing together the free;

edges of said side plates, and a base plate hinged at one edge to one ofsaid plates and provided ywith an aperture to engage: with a lightingixtureand thereby support` I second named plates being 1n allnement andsaid shade.

2. v In a collapsible shade, the combination with a main plate, of aplurality of side plates hinged to the side edges of the main plate,means for securing together the free edges of said side plates, and two.parallel base plates each hinged at onev edge to one of said plates,said base plates being provided with alining apertures and adapted toengage a lighting fixture and thereby support said shade in distendedcondition around the light.

8. A polygonal collapsible shade comprising a trapezoidal main platewith a plurality of trapezoidal side plates hinged to the non-paralleledges of the main plate and adapted to have the free edges of the sideplates swung into engaging contact to form a hollow polygonal sidedfrustum of a pyramid, and a base plate hinged at one edge to the mainplate and provided with a substantially centrally located aperture forengagement with and to permit sai-d base plate to be supported by thedesired lighting fixture.

4t. A three-sided collapsible shade comprising a trapezoidal main platewith two trapezoidal side plates, one hinged to each of the non-paralleledges of the main plate and adapted to be swung into position so thattheir free edges are in engaging contact so that lthe whole forms ahollow threesided frustum of a pyramid, and a triangular base piecehinged to themain plate,

and provided with a centrally located aperture by which it may beengaged with the desired lighting fixture, substantially as described.

Y 5. A three-sided collapsible shade comprising a trapezoidal main platewith two plate so that both apertured plates may enl gage with thedesired lighting iixtures, substantially as described.

V6. In a device of the class described, a main plate, a base platecarried by said main plate, said base plate bei-ng apertured andprovided with a collar located around said aperture, and a second baseplate located above the first base plate and provided with an aperture,said apertures in the base and adapted to fit on a lighting fixture.

7. In a device of the class described, a main plate, a base plateapproximately triangular in form and hinged at one edge to said mainplate, a second plate triangular' in form also hinged at one edge tosaid main plate above said bas-e plate.

8. In a device of the class described, a main plate, a base plate hingedat one edge to said main plate, a second plate located above said baseplate and hinged to the main plate, said base and second named platesbeing apertured and each provided with a collar around said apertures,and a pair of side plates each hinged at one edge to the main plate andbeing provided with a depression adapted to fold over a collar on eachsid-e of the main plate, said base plate being adapted to be folded overon to one side of the main plate under one I,ot said side plates andsaid second named plate being also adapted to be swung over 'on theopposite side of said main plate, the

collars on said base and second named plates being adapted to seat inthe depressions in said side plates.

In testimony whereof, I have subscribed my name.
